LEAD-UNED YARN-BEAM.

Specification of Letters'latent.

Patented Dec. 5, 1916.

Application led September 10, 1914.. Serial N o. 861,078.

To all whom t may concern Be it known that we, EUGENE HoLT and -L.\FAYETT.E HoLT, citizens of the United expedient for purposes of economy to em ploy hasemetals and similar materials which can be molded or cast in the desired form at comparatively small expense, but such materials are objectionable from`4 the fact that being exposed to the chemicals necessary to the proper treatment of the yarn, .the beam, and more especially that portion of the beam with which the yarn contacts, becomes corroded, and this corrosion or stain incident thereto communicates itself to the yarn and renders the latter commercially inferioror unfit for' use, thereby involving a certain percenta of loss in the product.

The object of the present invention is to avoid these disadvantages and prevent .deterioration of the productor any part of it, while providing for a construction of yarnl beam which shall be of 'a cost which is little, if a ny, in excess of those produced under the methods heretofore practised, and wherein `the means Iprovided for the protection of the yarn or contents of the beam shall be of such a character' as to permit of the comparatively rough or coarse formation of the body portion of the beam wherein .the strength of uthe structure resides.

With this object in view, the invention consists in a certam construction and arrangen'ient of parts hereinafter fully eX- pl ained, itbeing understood that changes inthe form, proportions and details of the construction may .be resorted to within the scope of the claims, without departing from the spirit of the invention or sacriiicing any of the advantages'thereof.

In the accompanying drawing, Figure 1 is a vertical sectional view of a'yarn beam arranged in its norm'al or operative position within a vat or retort which may be employed in the lvarious dyeing and other operations to which the yarn is subjected, said vat or retort being indicated by dotted lines; Flg, 2 is an end view of the beam yon the line 2-2 of Fig. l.; Fig. 3 is a transverse sec.- tional view'showing the inner surface of one of the heads on the plane indicated by the line 3-3 of Fig. 1'; Fig. 4 is a detallenlarged fragmenta] section of the beam barrel.

The hoop-shaped body portion of the yarn beam may be cast or the barrel portion 10 thereof may be drawn, rolled' or otherwise constructed with the heads 1l cast or stamped andsuitably fitted andsecured thereto, said heads in the construction illustrated consisting of a liub 12, ring or rim 13 and spokes 14, the' ends of the barrel being tted with plugs 15 and 16 of which the latter, when used as contemplated (namely for the in troduction or removal of the dye liquors through o'ne end of the barrel), shouldbe perforated,-.as indicated at 17. The barrel also is perforated more or less uniformly, or to a greater or less extent as may be found expedient in practice to permit of the passage of the dye and other -liquors therethrough either outwardly or inwardly, 'as

may be preferred, to insure the proper distribution of `said liquors throughout the bod)7 of the yarn which is wound or otherwise placed upon the exterior of the bargl between the planes of the heads, and is thereby held during the treatment to which the yarn is subjected.

Regarding the exterior surface of the barrel and the inner or facing surfaces of the heads as the bearing'surfaces or yarnholding surfaces of the beam, this invention contemplates providing said surfaces with a coating or sheath of a material which is non-corrosive or is not affected by the chemicals andother materials to which the yarn is subjected in treatment, such a sheath be-v ing indicated in the drawing at 18 and the ,same being extended outward at the inner surfaces of the heads to form disk-like plates 19. It'has been found, again as a matter of economy, that this sheath may be made of lead or a composition thereof, applied either as a coating'or as aslieet to the indicated surfaces of the body or main structure of the beam, and it is only with this sheath that the yarn comes in Contact duringv the described operations. As the corrosion to"`which the metal formingthe body of the beam is subjected is not communicated to the yarn except when the latter comes into actual contact therewith, a sheath arranged as de- BEST AVMLABLE co9' scribed formsa complete protection, and obvipusly the natural qualities of lead render it readily workable in providing a perfectly.'

smooth surface finish, which still further adds to the efficiency of the beam for the intended purposes. ties of lead and similar non-corrosive materials are inappropriate and impraetioable as materials for forming the body portion of the beam, owing to the comparatively rough usage and strains to whichsuch structures are subjected, they are not only suitable but peculiarly adapted to` the purpose herein de scribed when employed as a sheath to form the yarn-bearing surfaces of the beam, and While adding to the efficiency of the beam in preventing injury to'or deterioration of the yarn, add substantially to the durability and period of usefulness of the device.

What is claimed as new is:

l. A yarn beam having a body portion of Thus while the quali,-`

and terminal heads provided ontheir yarnbearing surfaces with asheath of substantially impervious non-,corrosive material.

5. A yarn beam havmg a `perforated barrel closed at one end and having an in-l let' at the other end and fitted with terminal heads, and. a sheath of nonfcorifosive metal arranged upon the exterior st rifaoe of the barrel and the facing surfaces of the heads, the barrel covering portion thereof being perforated in registration with the perforartions of the barrel.

6.l A ryarn beam' provided with a bearing surface of non-corrosive metal.

7. A 4yarn beam .provided with ra yarn bearing surface ofnonfcorro'sive metaland including a perforate barrel f 8. A yarn ybeam provided with a yarn bearing surface of substantially impervious non-corrosive material. n 4 y 9. A yarn beam having a perforate barrel,

sive sheath provided on they yarn bearing surface of the beam. l
